The X-wing books certainly had rebel protagonists, however certain events occurred (spoilers ahead) such as Ysanne Isard plotting an ambush, where she enlisted the full flight of TIEs because even she thought that a 6:1 ship ratio was necessary. Granted, it was rogue squadron, but other major squads were comprised nearly entirely of rookies and still proved their worth.
The whole purpose of the TIE concept was to overcome with numbers, so you can bet there were hundreds. Additionally, the Rebels had to continually dodge turbolaser fire, mucking up their attack runs. Darth Vader could have destroyed everyone except Luke and Wedge were time not of the essence "best starfighter pilot in the galaxy" style. Also, it was a flight of X-wings with literally 10 minutes to prep ships, formulate a plan and go for it. I'm not saying that X-wings were supersoldiers, but 3:1 even odds for an X-wing pilot doesn't match the 2:1 seen in the game.
Vader also one shots a Y.
Guys its a movie.
2:1 in this game seems fine.
We should play some wave 1 XXBB vs 7 Howl swarm.
